2015 European Microwave Conference (EuMC), 2015•ieeexplore.ieee.orgIn this paper, we demonstrate a 300-GHz FM-CW radar using optical modulation technology.
An optical frequency comb based on the optical modulation is utilized as a broadband
frequency multiplier with a factor of 12. At a central frequency of 300 GHz, we generate a 12-
GHz-bandwidth FM-CW signal with a pulse duration of 10 μs, realizing a precise ranging
with a resolution of several centimeters. We show that the optical frequency comb generator
is capable of generating larger bandwidth FM-CW signals.
